Anycubic Photon Mono 4 Ultra review
The faster Mono 4: ACF film and a release algorithm raise the stated top speed to 120 mm/h, on the same 17 × 17 µm 10K screen, with a COB and Fresnel light.
The panel stays the same. The film, the light and the checks change. ACF film and a release algorithm lift the stated top speed to 120 mm/h, and the COB with Fresnel lens system raises the light uniformity.
Why uniformity matters
Anycubic prints a figure of at least 90%. An uneven screen cures the edges of a plate differently from the center, and that shows up in dimensions.
The checks
The listing names five inspections, including printer auto-inspection. They are there to catch a failed print before it wastes a vat of resin.
Where it earns its place, and where it falls short
Strengths
ACF film for easier release
A light uniformity figure, which is rare
Five automatic inspections before and during a print
Compromises
The 120 mm/h peak depends on the resin
Costs more than the plain Mono 4
No build volume in the bullets of this listing

Questions makers ask before buying
What is ACF film?
A release film between the resin and the screen. Anycubic says it reduces frosting and lets more light through for a smoother release.
Does it share the Mono 4’s screen?
Yes on the published figures: 7 inches, 9024 × 5120 pixels and 17 × 17 µm.
Our score
8.1/ 10
A real step up from the Mono 4 if you print often. For occasional prints the plain model is enough.
